Title: IMAGE PROCESSING DEVICE, IMAGE PROCESSING METHOD, AND ELECTRONIC APPARATUS
Abstract:
The present technology relates to an image processing device, an image processing method, and an electronic apparatus for making it possible, when a wide dynamic range (WD) image is generated by composing a large-pixel pixel signal and a small-pixel pixel signal, to suppress degradation of the image quality of the WD image. An image processing device according to a first aspect of the present technology is provided with: a first acquisition unit which acquires a first pixel signal output from a first pixel; a second acquisition unit which acquires a second pixel signal output from a second pixel smaller in size than the first pixel; a temperature detection unit which detects temperature; a composition gain determination unit which determines a composition gain corresponding to the detected temperature; and a composition unit which composes the first pixel signal with the second pixel signal multiplied by the composition gain. The present technology may be applied in a CMOS image sensor, for example.
